The backlight module is an important component of a display device (such as a liquid crystal television), and is generally composed of a back plate 10, a light bar 40, a reflector 20, and the like, wherein the light bar 40 is generally mounted on the inner side of the back plate 10 by means of glue bonding or screwing. However, in order to obtain a sufficiently large installation space, the back plate 10 is generally designed to have a concave structure, so that the edge of the back plate 10 is formed into an inclined wall, an R angle transition exists between the inclined wall and the main body of the back plate 10, and accordingly, a portion of the reflecting sheet 20, which is installed inside the back plate 10 and corresponds to the inclined wall, is also an inclined surface, on one hand, because the tolerance of the R angle of the back plate 10 is large, in order to avoid that the R angle interferes with the installation of the light bar 40, the distance from the light bar 40 to the inclined wall of the back plate 10 cannot be too close, thereby causing space waste, and on the other hand, because the distance from the light plate 41 to the inclined wall is too large and is limited by the space between the inclined wall and the inclined surface, the reflecting sheet 20 needs to be provided with a notch for accommodating the wiring seat 42 of the light bar 40, however, the existence of the notch can cause problems such as light-emitting and shadow, and the like, which affect the display effect.

In view of the above problems, this solution proposes an improved light bar mounting structure 100, by manufacturing the supporting protrusion 14 on the inner side of the back plate 10, and then mounting the mounting end 411 of the light bar 40 on the supporting protrusion 14, so that the supporting protrusion 14 can raise the mounting end 411 of the light bar 40, so that the mounting end 411 of the light bar 40 is as close to the inclined plate 12 of the back plate 10 as possible, and the mounting end 411 and the wiring seat 42 mounted thereon extend into the accommodating space 30 formed by the inclined plate 12 of the back plate 10 and the inclined surface 21 of the reflector 20, i.e. interference between the mounting end 411 and the R angle is avoided, and meanwhile, the wiring seat 42 is avoided from the inclined surface 21, so that a notch is not required to be opened on the reflector 20 to avoid the wiring seat 42, thereby improving the space utilization and improving the display effect.

Referring to fig. 1, 2 and 4-6, a light bar mounting structure 100 according to an embodiment of the application includes a back plate 10, a reflective sheet 20 and a light bar 40. The back plate 10, the reflecting sheet 20 and the light bar 40 are all main components of a backlight module of a display device (such as a liquid crystal television), wherein the back plate 10 mainly has the following functions of providing support, namely, the back plate 10 is used as a basic structure of the backlight module and can provide stable support so that other components such as the reflecting sheet 20, the light bar 40 and the like can be correctly installed and fixed, and providing heat dissipation, namely, the back plate 10 is usually made of a metal material and has good heat dissipation performance, the heat dissipation performance can help the light bar 40 to dissipate heat, the temperature of the backlight module is kept in a proper range and the overheating is prevented, and further, providing isolation, namely, the back plate 10 can play a role of isolating, preventing light rays of the light bar 40 from penetrating to other parts and ensuring that the backlight only illuminates the area behind a liquid crystal screen.

The light bar 40 is a key component for providing a backlight light source, and has the functions of providing a light source, namely, the light bar 40 is a light source in a backlight module, can provide backlight light to illuminate an image behind a liquid crystal screen, and providing uniform backlight, namely, the light bar 40 can provide uniformly distributed backlight to ensure that the brightness of the surface of the liquid crystal screen is more uniform, so that uneven brightness can be avoided, the image quality and viewing experience can be improved, and the brightness of the light bar 40 can be controlled by adjusting parameters such as current, voltage and the like for adjusting the brightness and contrast, so that the brightness and the contrast of a liquid crystal television can be adjusted.

Specifically, in this case, the back plate 10 is rectangular, and the reflective sheet 20 is correspondingly rectangular. The light bars 40 are also rectangular, but when the light bars 40 are installed, the length direction of the light bars 40 is consistent with the length direction of the back plate 10, and a plurality of light bars 40 are arranged at equal intervals along the width direction of the back plate 10. A plurality of light bars 40 are simultaneously arranged to obtain a more abundant light source intensity. The light bar 40 is installed between the back plate 10 and the reflective sheet 20.

With continued reference to fig. 1 and 7, the light bar 40 includes a light plate 41 and a connector holder 42. In addition, a plurality of lamp beads 43 are arranged on the lamp panel 41 at intervals along the length direction, and when the wiring seat 42 is electrically connected with the control device, the lamp panel 41 is electrified, so that the lamp beads 43 can be lighted.

In order to avoid shielding, the reflecting plate 20 is provided with windows 22 at positions corresponding to the lamp beads 43, and each lamp bead 43 extends out of the corresponding window 22.

With continued reference to fig. 1, 5 and 7, the back plate 10 includes a plate body 11 and an inclined plate 12, wherein the plate body 11 approximates a flat plate structure, and the inclined plate 12 is inclined toward the inner side of the plate body 11 to provide a more abundant installation space for the back plate 10, so that the back plate 10 is integrally formed into a concave structure.

Specifically, the edge of the plate body 11 is a support portion 111, the support portion 111 is specifically located at two ends of the plate body 11 in the longitudinal direction, and the surface of the support portion 111 is provided with a support protrusion 14. The inclined plate 12 is connected to the edge of the support portion 111 and is inclined toward the inside of the back plate 10, and a transition rounded corner 13 (i.e., the aforementioned R-angle) is formed between the inclined plate 12 and the support portion 111.

Alternatively, the supporting protrusions 14 may be provided in a regular shape such as a cylinder, a circular truncated cone, or other irregular shapes, and may be selected according to actual needs.

The reflection sheet 20 is disposed inside the back plate 10, and a slope 21 is provided at a side of the reflection sheet 20. It will be appreciated that the reason why the inclined surface portion 21 is provided on the reflective sheet 20 is to adapt to the concave structure of the back plate 10, thereby facilitating the normal mounting of the reflective sheet 20 on the back plate 10.

The inclined surface portion 21 is disposed at a distance from the supporting portion 111 and encloses a receiving space 30. The lamp panel 41 includes a mounting end 411, the wiring seat 42 is disposed at the mounting end 411, and the mounting end 411 extends into the accommodating space 30 and is erected on the supporting protrusion 14. Specifically, the area of the accommodation space 30 near the inclined plate 12 includes a mounting area in which the wire holder 42 is disposed, the height of which varies increasingly from the side of the support 111 away from the inclined plate 12 to the direction of the inclined plate 12 (i.e., the direction of arrow S in the drawing). The mounting end 411 is disposed above the transition fillet 13, and the supporting protrusion 14 is configured to raise the lamp panel 40 relative to the supporting portion 111, so that the mounting end 411 can abut against the inclined plate 12 or be in clearance fit with the inclined plate 12 in the S direction, so that the wiring socket 42 can be completely accommodated in the mounting area of the accommodating space 30.

In summary, implementing the technical solution of the embodiment has the following advantages that in the light bar installation structure 100 of the embodiment, since the support portion 111 is formed at the edge portion of the board main body 11 of the back board 10, and the support portion 111 is convexly provided with the support protrusion 14, when the light bar 40 can be installed inside the back board 10, the support protrusion 14 can directly support the installation end 411 of the contact light board 41, thereby forming installation positioning for the light bar 40, and meanwhile, compared with the support portion 111, the support protrusion 14 can raise the installation position of the light bar 40; on the basis, the reflector 20 is mounted on the inner side of the back plate 10, the inclined surface part 21 of the reflector 20 can be arranged at intervals with the supporting part 111 and form the accommodating space 30, at the moment, the mounting end 411 and the wiring seat 42 arranged on the mounting end 411 are both positioned in the mounting area of the accommodating space 30, because the height of the mounting area of the accommodating space 30 is gradually changed along the direction from one side of the supporting part 111 away from the inclined plate 12 to the inclined plate 12, and the supporting bulge 14 can jack the mounting end 411 and suspend above the transition fillet 13, the mounting end 411 of the lamp panel 41 can be made to be close to the inclined plate 12 as much as possible and abut against the inclined plate or be in clearance fit with the inclined plate in the S direction, so that the inner side of the back plate 10 is utilized more fully, and meanwhile, the transition fillet 13 and the mounting end 411 are prevented from being interfered, and because the mounting end 411 can be arranged closer to the inclined plate 12, the wiring seat 42 on the mounting end 411 can be fully extended into the accommodating area of the accommodating space 30, the height of which is larger than the mounting end 411, and the wiring seat 42 can be fully extended into the accommodating space 30, and the mounting end 42 can be fully matched with the inclined surface part 42 (e.g. the wiring seat 20 is just completely matched with the inclined surface part 20), therefore, a notch is not required to be formed on the reflecting sheet 20 to accommodate the wiring seat 42 so as to prevent interference, so that the problems of light emission, shadow and the like caused by the existence of the notch are solved, and the display effect is improved.

Referring to fig. 5, with the benefit of the inclined posture of the inclined plate 12, when the supporting protrusion 14 lifts the mounting end 411 of the lamp panel 41 higher, the distance between the end surface of the mounting end 411 facing the inclined plate 12 and the plate surface of the inclined plate 12 is larger, so that the mounting end 411 can move horizontally leftwards (i.e. in the S direction) to be closer to the inclined plate 12, thereby driving the wiring seat 42 to translate leftwards synchronously, and the larger the height of the left area of the accommodating space 30 is, the mounting end 411 and the wiring seat 42 can be well accommodated, and meanwhile, the wiring seat 42 can be farther away from the inclined surface 21 of the reflector 20 to maintain the interference preventing distance.

On the basis of the above embodiment, the support projection 14 has a support surface away from the support portion 111, which is in supporting engagement with the back surface of the lamp panel 41. The back of supporting surface and lamp plate 41 is plane contact, and support stability is good to guarantee that support protrusion 14 is installed firmly to lamp plate 41.

For example, the supporting surface may be any one of a circle, a square, a triangle, etc., and the supporting surface is a horizontal plane, so that the supporting surface can be attached to the back plane of the lamp panel 41, so as to obtain a better supporting effect.

It should be noted that, according to practical needs, the supporting protrusions 14 may be provided in more than one, for example, two, three or more supporting protrusions 14 may be provided at the same time, but the arrangement manner of the two or more supporting protrusions 14 is not particularly limited, so long as it is ensured that the two or more supporting protrusions 14 can simultaneously support the stable light bar 40.

Further, in order to improve the mounting firmness of the light bar 40 on the supporting protrusion 14, the back surface of the light plate 41 is provided with an adhesive member, and the back surface of the light plate 41 is adhered and fixed to the supporting surface by the adhesive member. The adhesive member provides adhesive force to adhere and fix the lamp panel 41 to the supporting boss 14, preventing the lamp strip 40 from being displaced from the supporting boss 14 under vibration or the like.

Alternatively, the adhesive may be, but is not limited to, double sided tape, glue, or the like.

Of course, in other alternative embodiments, the lamp panel 41 and the supporting protrusion 14 may be assembled and fixed by vacuum adsorption, magnetic attraction, mechanical clamping, etc.

Alternatively, as shown in fig. 5, the back surface of the lamp panel 41 is concavely formed with a positioning groove 412, and the end of the supporting protrusion 14 away from the supporting portion 111 is disposed in the positioning groove 412. That is, by providing the positioning groove 412 such that the end portion of the supporting protrusion 14 is inserted into the positioning groove 412 to form a tight fit relationship with the groove wall of the positioning groove 412, the lamp panel 41 can be mounted and fixed, so as to improve the mounting stability of the lamp strip 40 on the supporting protrusion 14.

With continued reference to fig. 5 and 7, in accordance with any of the above embodiments, the preferred terminal block 42 is disposed adjacent the end face of the mounting end 411 opposite the angled plate 12. That is, the wire holder 42 is preferably disposed near the edge of the mounting end 411 facing the inclined plate 12, so that when the supporting protrusion 14 needs to be designed to have a smaller height, the mounting end 411 needs to be horizontally moved toward the inclined plate 12 for a smaller distance, so that the wire holder 42 is more significantly away from the inclined surface 21, thereby avoiding the reflective sheet 20, so as to avoid interference with the reflective sheet 20 or needing to form a notch on the reflective sheet 20 to avoid the wire holder 42.

In addition, the height of the supporting protrusion 14 is reasonably controlled, so that the lamp strip 40 is prevented from forming a larger gap far from the plate main body 11, and the waste of the installation space on the inner side of the back plate 10 is avoided, namely, the reasonable layout and the full utilization of the space of the lamp strip 40 on the inner side of the back plate 10 are realized.

The wiring seat 42 arranged on the lamp panel 41 is used for being connected with the controller point through a connecting wire, so that the lamp strip 40 is powered and the working states of the lamp strip 40, such as on and off, light intensity and the like, are controlled.

In the conventional art, the wire connection portion 421 of the wire connection seat 42 is disposed directly towards the inclined plate 12 of the back plate 10, so in order to facilitate the wire connection operation, at least one finger position (i.e. a space for accommodating a finger) needs to be reserved between the wire connection seat 42 and the inclined plate 12, and the finger position occupies space, so that the mounting end 411 of the lamp panel 41 and the wire connection seat 42 cannot be too close to the inclined plate 12, which also results in too close distance between the wire connection seat 42 and the inclined plate 21, and the reflector 20 is required to be notched to accommodate avoiding the wire connection seat 42.

Specifically, the connection portion 421 may be configured as a connection slot, a connection terminal, or the like. The wiring seat 42 is horizontally rotated by 90 ° (i.e. deflected by a preset angle) along the front surface of the lamp panel 41, so that the wiring portion 421 can be aligned to the inclined plate 12 from a direction opposite to the inclined plate 12, so that the wiring direction is perpendicular to the inclined plate 12, and the wiring portion 421 is deflected to be parallel to the plate surface of the inclined plate 12, so that the wiring direction and the inclined plate 12 are arranged at intervals side by side, and when the lamp bar 40 is mounted, the wiring operation can be performed in a wide space on one side of the width direction of the lamp bar 40 without interference blockage by the inclined plate 12, thereby facilitating the wiring operation.

It should be noted that, the inclined plates 12 and the supporting portions 111 are provided at opposite ends of the plate body 11 in the longitudinal direction, and correspondingly, the inclined portions 21 are provided at opposite ends of the reflecting sheet 20 in the longitudinal direction, and the supporting portions 111 at both ends are provided with the supporting protrusions 14, so that the mounting support can be formed at the same time for the opposite ends of the light bar 40 in the longitudinal direction.

With continued reference to fig. 5 and 7, in addition, on the basis of any of the above embodiments, the inner side wall of the back plate 10 is formed with a reinforcing rib 50, and the supporting protrusions 14 are disposed on the reinforcing rib 50. By manufacturing the reinforcing ribs 50 on the inner side wall of the backboard 10, structural reinforcement of the backboard 10 can be realized, the thinned structure and the material selection design of the backboard 10 are met, and meanwhile, the strength of the backboard 10 is ensured to be high enough, so that deformation is not easy to occur.

As shown in fig. 7, further, one end in the longitudinal direction of the reinforcing rib 50 is formed in the support portion 111 in the above-described embodiment, and the other end in the longitudinal direction of the reinforcing rib 50 (i.e., the direction of arrow W in fig. 7) extends to the inclined plate 12. Because the inclined plate 12 is connected to the edge of the supporting portion 111 in an inclined manner, and a transition fillet 13 is formed between the inclined plate and the supporting portion 111, the part of the structure is a weak strength, and is easier to deform under the action of external force extrusion or impact, so that the reinforcing rib 50 is arranged to span the transition fillet 13 from the supporting portion 111 and extend onto the inclined plate 12, so that structural reinforcement can be formed on the bent structure, and the capability of the back plate 10 for responding to external pressure or impact is improved.

With continued reference to fig. 3, in yet another embodiment, a groove 60 is formed on the outer side of the back plate 10 corresponding to the reinforcing rib 50, and a concave hole 70 is formed on the bottom wall of the groove 60 corresponding to the supporting protrusion 14. Compared with the mode of installing and fixing the independent supporting protrusions 14 on the inner side wall surface of the back plate 10 by welding and the like, the application can enable the back plate 10, the reinforcing ribs 50 and the supporting protrusions 14 to be processed (such as stamping) and formed at one time by reasonably designing the die structure, reduce processing difficulty and cost, reduce process steps, improve the production and preparation efficiency of the back plate 10, and further enable the back plate 10, the reinforcing ribs 50 and the supporting protrusions 14 to obtain better overall structural performance.

In addition, the present application also provides a display device, which includes the light bar mounting structure 100 according to any of the embodiments.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
